A because idn hope u find the answer
Answer:
No
Explanation:
During cyclic photophosphorylation, electrons are cycled continuously out of and back into the reaction center of PSI. It does not involve PSII and plastoquinone. During non cyclic photophosphorylation, the reaction center of plant photosystem II passes electrons to plastoquinone. The reduced plastoquinone carries electrons to the cytochrome b6f complex. Since PSII and plastoquinones are not included in cyclic photophosphorylation, dichlorophenyldimethylurea would not affect the process.

Answer:
peptide antigens by MHC class II molecules

Helper T cells are activated by peptide antigens by MHC class II molecules. These antigens express on the surface of antigen-presenting cells (APCs). After activation, the T helper cells divide and secrete cytokines to assist the immune response.
Because it has no seed or have seeds with wax coating that helps prevent water loss. So it would be the one that says , It has a waxy material that prevents the loss of water to the environment. because that is true.
